Configuring Power Stack Switch Power Parameters - Cisco Catalyst 3750-X Software Configuration Manual

Chapter 9 Configuring Catalyst 3750-X StackPower
This is an example of setting the stack power mode for the stack named power1 to redundant power
mode. The largest power supply in the stack is removed from the power budget and used as a backup in
case of power supply failure.
Switch(config)# stack-power stack power1
Switch(config-stackpower)# mode redundant
Switch(config-stackpower)# exit

Configuring Power Stack Switch Power Parameters

Beginning in privileged EXEC mode, follow these steps to configure a switch in a power stack:
Command
Step 1 configure terminal
Step 2 stack-power switch switch-number
stack [power-stack-name]
Step 3
Step 4 power-priority switch value
Step 5
power-priority high value
Step 6
power-priority low value
Step 7 end
Step 8
show stack-power
Step 9
copy running-config startup-config
This is an example of setting the switch stack power parameters for switch 3 in the stack that is connected
to the power stack with the stack ID power2. If load-shedding becomes necessary, switches and powered
devices in the power stack with the higher numbers are shut down first, with shutdown proceeding in
order.
Switch(config)# stack-power switch 3
Switch(config-switch-stackpower)# stack power2
Switch(config-switch-stackpower)# power-priority switch 5
Switch(config-switch-stackpower)# power-priority high 12
Switch(config-switch-stackpower)# power-priority low 20
Switch(config-switch-stackpower)# exit
Switch(config-stackpower)# exit
OL-21521-01
Purpose
Enter global configuration mode.
Enter the stack member number of the switch in the power stack and
enter switch stack power configuration mode. The range is from 1
to 9.
Only four switches can belong to the same power stack.
Note
Enter the name of the power stack to which the switch belongs. The
name can be up to 31 characters. If you do not enter a name and no
other switches in the power stack have a name configured, a
power-stack name is automatically generated.
Set the power priority of the switch. The range is from 1 to 27. This
value must be lower than the value set for the low and high-priority
ports.
Set the power priority of the PoE ports on the switch that are
configured as high-priority ports. The range is from 1 to 27, with 1
as the highest priority. The high value must be lower than the value
set for the low-priority ports and higher than the value set for the
switch.
Set the power priority of the PoE ports on the switch that are
configured as low-priority ports. The range is from 1 to 27. This
value must be higher than the value set for the low-priority ports
and the value set for the switch.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
